Buy the Megger MIT1525 15 kV insulation resistance tester in the UAE from MME, an authorized Megger representative. Browse our Megger range and insulation resistance testers for related models.

Overview

The Megger MIT1525 is a high-performance 15 kV DC insulation resistance tester for power generation, transmission and distribution assets. It measures insulation resistance up to 30 TΩ, supports diagnostic modes including IR, DAR, PI, DD, SV and ramp, and uses Megger’s PI Predictor (PIp) to shorten polarisation-index tests. Dual-case construction, CAT IV 1000 V rating and battery or mains operation make it practical for transformers, motors, generators and HV cables in the field.

Key Features

The MIT1525 delivers diagnostic 15 kV insulation testing with productivity-focused design:

Test voltage to 15 kV — user-defined steps from 1000 V to 15 kV (100 V / 25 V steps by range)
Resistance to 30 TΩ at 15 kV with PI Predictor (PIp) for faster PI testing
Full diagnostic suite — IR, IR(t), DAR, PI, SV, DD and ramp test modes
CAT IV 1000 V safety rating to 3000 m; dual-case design for added protection
Battery or AC mains operation with rapid-charge Li-ion packs (about 4.5 h at 15 kV / 100 MΩ load)
Advanced memory with time/date stamp, USB download and CertSuite Asset compatibility
IP65 (lid closed) / IP40 (lid open); short-circuit / charge current 6 mA at 15 kV

Applications

Use the MIT1525 wherever high-voltage insulation condition matters:

Insulation testing of transformers, motors, generators and HV cables
Commissioning and maintenance in generation, transmission and distribution
Diagnostic trending with PI, DAR, DD, step voltage and ramp tests
Documented asset testing with on-board memory and software export
